Service Intervals General
Oil Change Interval:
Typically every 5,000 miles (8,000 km) or 6 months, whichever comes first, or using the vehicle's oil life monitoring system.
Air Filter Replacement:
Recommended every 15,000 - 30,000 miles (24,000 - 48,000 km) or as needed based on driving conditions.
Cabin Air Filter:
Recommended every 15,000 - 30,000 miles (24,000 - 48,000 km) or annually.
Spark Plug Replacement:
Iridium-tipped spark plugs typically have a longer service life, often around 75,000 - 100,000 miles (120,000 - 160,000 km).
Engine Oil Type:
0W-20 synthetic engine oil is typically recommended for the 2.5L engine. Check owner's manual for specific viscosity grade and API service classification.
Coolant Type:
Mazda Super Long Life Coolant (SLLC), or an equivalent ethylene glycol-based coolant with long-life additives, typically a pink or orange color.
Brake Fluid Type:
DOT 3 or DOT 4 brake fluid.
Common Problem 1:
Oil consumption in higher mileage 2.5L engines, potentially related to piston ring wear or PCV system issues. The manual will detail checks and potential fixes.
Common Problem 2:
Corrosion on the rear subframe and suspension components, especially in regions with road salt. Manual provides inspection points and repair procedures.
Common Problem 3:
